曲流河相沉积砂体由于其单层薄、横向上不稳定、变化大等特点 ,给实际的石油勘探开发和预测工作造成了很大的困难 .根据某油田曲流河砂体的沉积特点 ,利用人工神经网络技术和多种地震特征参数信息 ,对曲流河砂体的横向分布进行了预测和评价 ,钻探结果表明 ,与实际情况吻合较好
Meandering river sedimentary sand body has great difficulties for the actual petroleum exploration and development and prediction due to its thin single layer, lateral instability and large variation.According to the sedimentary characteristics of meandering river sand body in a certain oilfield, The lateral distribution of meandering sand body is predicted and evaluated by artificial neural network technology and various seismic characteristic parameter information. The drilling results show that it is in good agreement with the actual situation
